DescriptionCVE.org

A vulnerability was found in ahujasid blender-mcp up to 7636d13bded82eca58eb93c3f4cd8708dfdfbe8b. The affected element is the function requests.get of the file src/blender_mcp/server.py of the component ZIP File Handler. The manipulation of the argument zip_file_url results in server-side request forgery. The attack can be executed remotely. The exploit has been made public and could be used. This product implements a rolling release for ongoing delivery, which means version information for affected or updated releases is unavailable. The patch is identified as 5b37be25242e73dc4cf1328974d30458b9e5d67e. It is advisable to implement a patch to correct this issue.

AnalysisAI

Server-side request forgery in blender-mcp's ZIP File Handler allows authenticated remote attackers to manipulate the zip_file_url parameter in import_generated_asset_hunyuan, causing the MCP server to issue arbitrary outbound HTTP requests on behalf of the attacker - including to internal network resources such as cloud metadata endpoints. All rolling-release commits up to 7636d13bded82eca58eb93c3f4cd8708dfdfbe8b are affected, per CPE cpe:2.3:a:ahujasid:blender-mcp:*:*:*:*:*:*:*:*. …

Attack ChainAIDerived

Hypothetical attack flow derived from CVE metadata

Access
Obtain low-privilege authenticated session
Delivery
Submit crafted MCP tool call with internal zip_file_url
Exploit
Server invokes requests.get(zip_file_url) without validation
Execution
SSRF request reaches internal network target (e.g., cloud metadata service)
Persist
Attacker receives internal response containing credentials or configuration
Impact
Leverage exfiltrated data to escalate privileges or pivot laterally

Vulnerability AssessmentAI

Exploitation The CVSS vector PR:L confirms that exploitation requires low-privilege authenticated access to the blender-mcp MCP server - unauthenticated exploitation is not supported by available data. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 6.3 Medium score is grounded in the PR:L authentication requirement, which meaningfully constrains the attack surface relative to unauthenticated SSRF. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario A publicly available exploit exists via GitHub issue #203. An attacker with low-privilege authenticated access to a network-exposed blender-mcp MCP server submits a crafted tool invocation targeting import_generated_asset_hunyuan with zip_file_url set to an internal address such as http://169.254.169.254/latest/meta-data/iam/security-credentials/ (AWS IMDSv1). …
Remediation The upstream fix is available via PR #205 (https://github.com/ahujasid/blender-mcp/pull/205) and commit 5b37be25242e73dc4cf1328974d30458b9e5d67e (https://github.com/bergskenop/blender-mcp/commit/5b37be25242e73dc4cf1328974d30458b9e5d67e). … Detailed patch versions, workarounds, and compensating controls in full report.
